that's bad.....in my school you can choose either biology or IT

Err.....i am angry about this.... what's the school is going to lose if we didn't take Bio, at least let us decide our own way!

How shameful i was during last year, when the school said "Tak boleh drop bio" in front of many students...

The respiration system of the fish:

1. First of all, the stupid fish opens his mouth
2. Then, the ruang operkulum(operkulum is the thing that protects the insang) jadi besar and the bukaan operkulum tutup
3. When he opens his dumb mouth, his dasar mulut or whatever turun.
4. Then the water rushes into his mouth [and choke him(i wish....lol)]
5. Then he decides to close his mouth
6. Then somehow the otot operkulum mengecut or something and the ruang operkulum jadi kecil.
7. So, the bukaan operkulum buka.
8. The water rushes out because of the tekanan dalam ikan tinggi
9. When it rushes out, it passes the insang.
10. The aliran darah is anti-selari with the water so it can resap better
11. The oksigen and karbon dioksida resap masuk and keluar
12. Then the water goes out of his stupid mouth
13. TADA...!! The fish got oxygen for his stupid body.

Well, i can get ur meaning.
But, if come out in esei dun write like that, if not u will and the examiner will

chill dude...the fish is innocent...

But, I'm sure I will still get marks....
Oh well, at least I could actually remember how he does it......whee!

It is not, who asked it to be in the biology book?

i see your immense hatred for the fish.
i hate those about the plants.i'm not gonna be a gardener or something you know.geez.

the plant is quite easy lar.....
at least i can remember that during my trial...
now? i lose memory bout it.

i ALWAYS get confused which is the floem and which is the xilem.haha.simple stuff also i can get confused.at least i get the animals.like the ruminents and all.but plants...

which experiment dat u guys hoping 4? i hope dat asap rokok will come out...coz i hv read dat...haha..

hmm...i gt 1 formula for that....
just remember xilem dalam air....
which means XILEM di bahagian dalam, dan mengangkut AIR

i think persenyawaan ganda dua is a lot easier than da fishes...
i love pengkolonian dan penyesaran 4 da kolam but hate dat hutan bakau...
wat da heck is dat akar janjang...bijih benih vividparati...or something like dat...

erm,i've never heard of that vividparati thing.my god...i've to so go read up now.

I hope that DOESN'T come out. How is it done? Can you write it down here?

Anyway, just read about the penyesaran tasik and a bit of paya bakau(yea, I am reading in front of the computer, I read 10 pages, then check for new posts and then continue reading again...=p)

Sesaran Tasik:
1. Perintis(organisma pertama yang menduduki satu kawasan yang biasanya tidak subur), that is tumbuhan tenggelam like hydrilla sp.
2. Then, the kolam semakin cetek cos of the humus when the tenggelam plants die.
3. So, tumbuhan terapung comes about, such as teratai and lemna sp.
4. The tumbuhan terapung stops the cahaya matahari from going into the kolam, so all the hydrilla sp. die! =]
5. Then, the kolam semakin cetek again
6. Becomes too cetek for the terapung plants
7. Then, tumbuhan amfibia comes about such as rusigia and purun
8. Finally, the kolam too cetek already and soon it becomes land
9. So, tumbuhan like rumput and pokok renek comes
10. Finally, it becomes hutan hujan tropika.

Pengesuaian di paya bakau
1. Biji benih vivipirati(bercambah pada pokok)
2. pneumatofor, little thing sticking out of the water so that the akar can breathe
3. Lentisel, bukaan pada pokok untuk resapan udara
4. Akar yang luas to cengkam the soft tanah
5. Daun yang tebal dan sukulen cos of the cahaya matahari yang terik
6. Singkir the garam at the hidatod(epidermis bawah daun) cos of the air yang masin

Sesaran/pengkolonian pada paya bakau:

1. Avicienna sp. and sonneratia sp. (perintis, with pneumatofor)
2. Rhizophora sp. (akar jangkang)
3. Bruguiera sp. (akar banir with that lutut thing)
4. Nipah, kelapa
5. Hutan hujan tropika

Sistem pengelasan lima alam
1, Prokaryoatae(bakteria)
2. Animalia(haiwan multisel)
3. Plantae(tumbuhan multisel)
4. Fungi(kulat, cendawan...)
5. Protista(protozoa, alga like spirogira, paramecium)

Hierarki Pengelasan
1. Alam
2. filum
3. kelas
4. order
5. Famili
6. Genus
7. Spesies

tujuan: mengkajikesan asap rokok ke atas kapas putih dan menganalogikan keadaan kapas putih dgn keadaan peparu
masalah:apakah kesan asap rokok ke atas kapas putih?apakah analogi keadaan kapas putih dengan peparu?
hipotesis:kapas putih menjadi hitam apabila didedahkan kepada asap rokok
bhn&rds: kapas putih,rokok, larutan penunjuk semesta,tiub kaca,kelalang kon, pam turas, kaki retort, salur kaca, 2 gabus berlubang tunggal dan gabus berlubang dua.
teknik: memerhatikan perubahan warna pada kapas putih dan larutan penunjuk semesta
prosedur:
1.radas disediakan seperti dlm rjh.
2.rokok dinyalakan
3.pam turas dihidupkan perlahan2 supaya asap rokok ditarik ke arah kapas lembapdan larutan penunjuk semesta dalam kelalang kon.
4. slps rokok habis terbakar,perubahan warna kapas dan larutan penunjukj semesta diperhatikan.
5.keputusna dicatat dlm jadual

keputusan:
kapas putih-hitam
larutan penunjuk semesta-merah(berasid)

kesimpulkan: hipotesis diterima

why i said easy coz u can cheat the bhn&rds with write only wat u lukis and can cheat also the prosedur if u faham how da experiment going on.
i can't show da rjh but u can try look fokus u mls 164-165

u read in front da comp? i read+eat+read in front of da comp now..

Ok....I learned about the rokok already...not very hard...hehe =]
Thanks!

I'm now reading about the mikroorganima in bab 9 form 4
